DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows a writing instrument 10 that incorporates a pivotable writing implement. The writing instrument is provided with a case 12 including a first end portion 14 and a second end portion 16 that when joined define an enclosed interior space in which an item, such as a pair of eyeglasses can be placed. A writing implement 18 is attached to the first end portion. The writing implement pivotable about a hinge 20 between a writing position (FIG. 2) and a rest position (FIG. 1), in which the implement 18 is against the case. Here, a pin 21 extends through an aperture in the first end portion and the writing implement. When the first end portion is joined to the case, an enclosed interior space is defined, and when the first end portion is removed from the case the interior space can be accessed in order to remove the item from the interior space. See FIG. 3. The second end portion 16 may further be provided with an end wall 22 at the end opposite the writing implement, and the end wall may be integral with the second end portion. Additionally, a time piece may be positioned on the case, such as on the end wall 22. See FIG. 4.

To facilitate the joining of the first end portion 14 and the second end portion 16, one of the first or second end portions 14,16 may be provided with a slightly smaller outside perimeter at its opening relative to the outside perimeter of the other portion, so that it will form an interference fit with the other portion. As shown in FIG. 3, the second end portion 16 is provided with a slightly smaller perimeter 24 relative to the first end portion, but the roles can be reversed.

The writing implement at the first end portion can be a pen, pencil or any other known writing implement. While the present invention has been shown as providing an interior space for retaining glasses, it should be understood that other items may be place there, including, but not limited to, foods, medicines, thermometers, coins, notes, pocket knives, tire pressure gauges, to name only a few disparate items that evince the breadth of possibilities, which need not be exhausted here.

FIGS. 5, 6, and 7 show a multi-purpose container 30 having, in side-by-side arrangement, a first container portion 32 configured to receive a hand held electronic device, wherein the first container portion is provided with first half 34, a second half 36, and a hinge 38 joining the first half and the second half, the second half movable between an open position (FIG. 7) and a closed position (FIGS. 5 and 6), the first container portion 32 having an interior space 40 for receiving a hand held electronic device. The electronic device can be inserted and removed from the container portion by moving the second half between the open position and the closed position.

The multi purpose container 30 is further provided with a second container portion 42 adjacent the first container portion 32. The second container portion 42 is configured to receive a writing instrument 44, the second container portion being open on one side 46, through which the writing instrument can be inserted and removed from the second container portion.

FIGS. 8, 9, and 10 show the multi purpose container 30 of FIGS. 5-7 provided with a gauge to measure a parameter, such as time, temperature, positioning, humidity, barometric pressure, to name but few possibilities. As shown in the figures, the container is provided with a digital timepiece and a thermometer 48 on its depth side 50. In another embodiment, a computational device can be included, such as a calculator.

FIGS. 11, 12, and 13 show the multi purpose container 30 of FIGS. 5-7 provided with a gauge to measure a parameter, such as time, temperature, positioning, humidity, barometric pressure, to name but few possibilities. A computational device, such as a calculator, can also be employed. As shown in the figures, the container is provided with an analog timepiece 54 and a compass 56 on its top side 58

FIGS. 14, 15, and 16 show a container 60 having a first half 62 and a second half 64, the first and second halves each having hinge forming members 66 that are joined together to form a hinge 68, permitting the container to be opened and closed. The halves are constructed of a base 70 and a skirt 72 that extends around the perimeter of the base 70 in a direction perpendicular to the base. The hinge forming members 66 are located on one side of the base. When the container is in the closed position, the skirt of the first half 62 and the skirt of the second half 64 are in an abutting relationship. The hinge forming members 66 on the first and second halves 62, 64 define an open space on the inside of the hinge forming members, in which space a writing instrument, or other object sharing that configuration, can be positioned. This arrangement can be constructed by varying the diameter of one of the hinge forming members so that it fits in the other hinge forming member. The interior space between the first and second halves, hereinafter referred to as the first interior space 74, is sized and configured to retain a pair of eyeglasses, or other objects, including but not limited to notepads calendars, diaries, foods, medicines, maps, storage medium (digital or analog), to name but a few possibilities. The second interior space 76 can house an item configured like a writing instrument, including but not limited to a writing implement such as a pen, pencil, a thermometer, pressure gauge, flashlight, to name but a few possibilities.

FIGS. 17, 18, and 19 show a variation on the embodiment of FIGS. 14-16 by including gauges that measure parameters. Here, the gauges 78, 80 measure time and temperature. It should be understood that any kind of gauge may be employed, including those previously noted here. A computational device may also be placed where the gauge is placed.

FIG. 20 shows an exploded view of yet another embodiment of the present invention, which is a container 82 that, when not subjected to a force sufficient to flip it or turn it, remains in an upright position, or returns thereto. The container has a housing 84 having top 86 and bottom 88 zones, the bottom zone 88 having a rounded surface 90 constituting the bottom of the container. The bottom zone 88 is heavier than the top zone. The bottom zone can be made heavier than the top zone by including a metal weight into the bottom zone 88, or by constructing the bottom zone to have a density in excess of the density of the top zone. This can be accomplished by selecting the appropriate materials to achieve this result.

When the top and bottom zones are joined together (FIG. 23), the housing defines an interior space in which at least one item can be stored. In one embodiment, the housing is provided with a top zone that is separable from the bottom zone in order to permit access to the interior space. See FIG. 22. The top zone can be provided with a conical shape. It should be understood that the top zone can be provided with a lid that can be positioned on the opening, or removed therefrom, in order to access the interior space and/or items stored therein.

Because the bottom of the container is rounded, and heavier than the remainder of the container, the container will, if not subjected to an external force, rest on its bottom, and remain in an upright position. If the container is pushed, it will wobble and then return to its upright position.

In another embodiment, the container is provided with a gauge for measuring a parameter, such a timepiece 90, as shown in FIGS. 22-25. Alternatively, a computational device can be placed where the gauge is placed. In another embodiment, the container is provided with an opening 91 to receive a writing instrument. See FIGS. 22-24. In another embodiment, a pair of eyeglasses, or other item, can be stored in the container. See FIGS. 20-25. In another embodiment, the container is provided with compartments 92 for retaining the stored item in place. The compartment 92 may be a slot having circular sidewalls 94 that extend upward in the interior space from the bottom of the container, as shown in FIG. 24. Alternatively, the compartment 92 can be constructed out of a plurality of slot defining sidewalls 96 that extend upward in the interior space from a bottom of the container. See FIG. 24.

FIG. 26 shows a container for storing an item such as a pair of eyeglasses and a second container portion for storing an item having the configuration of a writing instrument.

In another embodiment, the body is provided with a second end closure 184, which can be of a pair of semicircles 186, each of which is attached to one of the halves. In another embodiment, the writing implement is provided with a gauge 188, such as a timepiece that is positioned to be visible when the writing implement is in the open position. That is, the writing implement is provided with a timepiece, or other gauge to measure a parameter, on its rear side. See FIG. 35. Alternatively, a computational device may be provided.

FIGS. 36-38 show a writing instrument 190 having a body 192 that defines an interior space in which an item, such as a pair of eyeglasses, or any other item, including those previously noted, can be placed. A writing implement 194 is positioned at the a first end 196 of the body 192, and is attached to the body 192 by a hinge 198. The writing implement is pivotable 194 between a writing position and an open position allowing for access to the container. In one embodiment, a gauge 200 to measure a parameter is attached to the end of the container. The gauge can be a timepiece, or any of the other gauges previously described. Alternatively, a computational device may be provided.

In an another embodiment shown in FIG. 37, the gauge 200 is positioned on the inward facing side of the writing implement 194. In yet another embodiment shown in FIG. 38, the writing implement is positioned on an end closure 202 on the end opposite the writing implement 194. The end closure is attached to the body by a hinge 204. Alternatively, a computational device may be provided.

It should be understood that embodiments combining features shown in FIGS. 32, 33 and 34-38 are possible. For example, the container can be provided with a body 152 having a length dimension L that is divided in two halves 154, 156 in a direction that intersects the body. The halves can be joined together to form a closed container, or separated to provide an open container. The container can also be provided with a writing implement positioned at the a first end of the body, and attached to the body by a hinge. The writing implement is pivotable between a writing position and an open position providing access to the container. In another embodiment, a gauge 200 to measure a parameter is attached to the end of the container, facing inward or outward, as previously described. The gauge can be a timepiece, or any of the other gauges previously described. Alternatively, a computational device may be provided.

FIGS. 39-41 show a writing instrument 210 having an off-axis writing implement 212 and removable first end 214 that allows for access to an interior space in which items can be stored. The writing instrument 210 is provided with a barrel 216 having an axis extending in the length direction L of the writing instrument. The barrel sidewalls 218 define an interior space for retaining and storing an item.

The writing implement is positioned off of the axis of the barrel, that is, it may be parallel to, but not the axis. At the first end of the barrel, an opening 220 is provided in the first end 214 in communication with the interior space.

A removable first end 214 is adapted to seal the opening 220 when it is placed on the first end of the barrel 216. The removable first end 214 can be removed from the barrel 216 to permit access to the opening 220, and the interior space. As shown in FIGS. 39-41, the removable first end 214 may be a cap 215 having a base 222 and a skirt 224 attached to the base 222 that, when joined to the barrel 216, seals the opening 220 from the exterior environment and encloses the writing implement 212 within the cap.

The interior space is configured to hold a pair of eyeglasses, or any of the other items previously mentioned.

In an alternative embodiment shown in FIG. 42, the removable first end 214 is a plug received over the opening, or within the opening. The tip 211 of the writing implement 212 is received within a recess 217 in the removable first end 214 when it is positioned within or over the opening.

FIG. 42 shows a writing instrument that is provided with a mirror 219. The mirror may be positioned near the tip 211 of the writing implement 212, or the mirror may cover the predominant portion of a barrel side. Although FIG. 42 shows a first end having a fingernail shaped housing in which the writing implement 212 is positioned, it should be understood that the other configurations are possible.

In yet a further embodiment of the invention, a gauge for measuring a parameter, such as a timepiece 228, is provided on one of the ends of the writing instrument. It can be provided on the removable first end 214 (FIGS. 39, 40) or the second end 225 (FIG. 41). Alternatively, a computational device may be provided.

FIGS. 43, 44, and 45 show a variation on the embodiments of FIGS. 39, 40, and 41 wherein the predominant portion of interior space is associated with the removable first end 214. In FIGS. 39, 40, and 41, the predominant portion of the interior space is associated with the barrel 216.

In yet a further embodiment, shown in FIGS. 46, 47, and 48, the writing implement 212 is attached to the barrel 216 by a hinge 230. The writing implement 212 is movable from an open position to a closed position. The writing implement 212 has a rear surface 232 that seals the opening 222 of the barrel when the writing implement is in the closed position.

FIG. 49 shows a folding eyeglass frame 240 in which the glasses, when in the open position (FIG. 49) are configured to be worn in the conventional manner, and a closed position (FIG. 54) in which the lenses and all or a substantial portion of the frame are enclosed within clam shell like portions 242 of the frame 240 that serve as the ear rest portions of the arms 244. When in the folded the state, it is not apparent that the resulting object, which resembles a clam, contains a pair of glasses. The compact form the glasses take, when folded, provides apparent space saving benefits.

The glasses are provided with a front frame 246 including a pair of lens retaining portions joined together by a hinged bridge 248. The hinged bridge is constructed of two hinge forming members 249, each of which extends from the inward side of the lens retaining members 250. The hinge forming members are provided with apertures which are placed in alignment with each other and joined together by a screw, pin, bolt, or other known devices for joining a hinge. The glasses can be folded along the hinge, as shown in FIGS. 52-54.

Arms 244 are attached to the outward sides of the lens retaining members 250 at hinges 251 in same manner as described with respect to the joining the hinge forming members at the bridge. The hinged arms can be moved out ward, in a configuration in which the glasses can be worn by the user, or moved inwardly, towards the lens retaining members.

The arms are constructed of a first relatively thin portion 252 that extends from the hinges 251. Concave shaped ear rests 254 are slidably mounted over the relatively thin portions 252. The concave shaped ear rests 254 have an open face 255 in the direction of the user's head.

After wearing the glasses, the user can fold them into a compact, space saving form, more easily stored than the unfolded form. The user slides the ear rests forward over the relatively thin portions of the arm (FIG. 51), folds the glasses inward at the hinges 251 so that the lens retaining members approach each other and eventually abut each other (FIG. 52) , and then folds the concave shaped ear rests 254 over the lens retaining members on the other side of the glasses (FIGS. 53 and 54). In this folded state, the edges 257 of the ear rests 254 abut each other, and the lens retaining members and other portions of the frame are enclosed within the ear rests.

FIG. 55 shows a container 270 for storing folding eyeglasses in a container that is provided with a cover portion 272, a base portion 274, and a gauge 278 for measuring a parameter, such as a timepiece or any of the others previously noted. Alternatively, a computational device may be provided. The gauge is positioned on the face of the cover portion 272. The cover portion 272 is attached to the base portion by a hinge 276. An item, such as a pair of folding eyeglasses, can be stored in the interior container space, and enclosed there when the cover is closed. Any of the other previously mentioned items can be stored there.

FIG. 56 shows a variation on the previous embodiment. Here, the timepiece 278 is positioned on the interior face 272 of the cover, and is visible only when the cover is in the open position.

The container can take any known shape. Exemplary are the square and rounded shapes shown in FIGS. 55, 56, and 57.

FIGS. 58 and 59 show a suitable writing implement 400 that can be used in several of the embodiments described herein. The writing implement includes and openable front cap and writing tip 402. The front cap includes a hollow rotary knob 404 and connecting element 406 that may be used to close an end of the container or barrel. The rotary knob 404 and connecting element 406 are interengaged so that the rotary knob can rotate relative to the connecting element 406. The connecting element 406 has a front end formed with a cylindrical tip mounting portion 408. The tip mounting portion 408 has an inner surface formed with two opposed substantially trapezoidal projections 410 such that two substantially trapezoidal recesses 412 are defined between the projections 410. Each projection 410 has a front end surface formned with a limiting depressed portion 414. The writing tip 402 has a front end portion fitted with a spring 416 for biasing the writing tip 402 to a retracted position, that is, retracted within the rotary knob 404. Further, the writing tip 402 has a rear end portion provided with two opposed, substantially triangular abutting protrusions 418 that fit into recesses 410. The connecting element 406 can be press fitted within the opening in the barrel or container. Rotation of the rotary knob 404 relative to the barrel or container against the biasing action of the spring, the writing tip 402 will rotate relative to the connecting element 406, while the abutting protrusions 418 are confined by the limiting depressed portions 414. At this time, the writing tip 402 will extend from a front end of the rotary knob 404, which is the write position. The rotary knob may be turned at any time to cause the abutting protrusions 418 to displace to the recesses 412 by virtue of the biasing action of the spring 416 so that the writing tip 402 retracts into the rotary knob 404.

From the foregoing, it can be appreciated that since access to the interior of the pen is from a lateral side of the pen, instead of from the rear end, arrangement of an additional functional accessory, such as a flashlight, eraser, etc., at the rear end of the pen is easier in terms of manufacture and assembly. Furthermore, the pen can assume a shape other that the conventional cylindrical shape so as to provide more variety in design choices. For instance, in the second preferred embodiment, the pen 5 has an interesting wavy or gourd-like shape.

FIGS. 75-78 show a folding eyeglass frame 240 in which the glasses, when in the open position (FIG. 75) are configured to be worn in the conventional manner, and a closed position (FIG. 78) in which the lenses and all or a substantial portion of the frame are enclosed within clam shell like portions 242 of the frame 240 that serve as the ear rest portions of the arms 244. When in the folded the state, it is not apparent that the resulting object, which resembles a clam, contains a pair of glasses. The compact form the glasses take, when folded, provides apparent space saving benefits.

The glasses are provided with a front frame 246 including a pair of lens retaining members 250 joined together by a hinged bridge 248. The hinged bridge is constructed of two hinge forming members 249, each of which extends from the inward side of the lens retaining members 250. The hinge forming members are provided with apertures which are placed in alignment with each other and joined together by a screw, pin, bolt, or other known devices for joining a hinge. The glasses can be folded along the hinge, as shown in FIGS. 76-78. Here, during folding, the hinged bridge 248 is positioned in the space where the user's head would be when in the open position of FIG. 75. This is in distinction to the embodiment of FIGS. 49-53 where, during folding, the lens retaining members 250 are positioned in the space where the user's head would be when in the open position of FIG. 49. In other words, lens retaining members fold inward in FIGS. 49-53. They fold outward in the embodiment of FIGS. 75-78. A clasp 221 can be provided on the case to keep the clam shell like portions 242 in a closed position.

FIGS. 79-84 shows another embodiment of folding eyeglasses having case members having the components aforedescribed: a front frame 246, lens retaining members 250 joined together by a hinged bridge 248, clam shell like portions 242 of the frame 240 that serve as the ear rest portions of the arms 244. The hinged bridge is constructed of two hinge forming members 249, arms 244 attached to the outward sides of the lens retaining members 250 at hinges 251, the arms being constructed of a first relatively thin portion 252 that extends from the hinges 251, and concave shaped ear rests 254 are slidably mounted over the relatively thin portions 252. The concave shaped ear rests 254 have an open face 255 in the direction of the user's head.

FIG. 85 shows the hinge 251. A spring 233 constructed of resilient and flexible material is attached to an end of the relatively thin portions 252 of the arms 244. The spring has a two wires 231 extending in the direction of the arm, and a portion 233 attached to each wire that extends substantially perpendicular to the direction of the wires. The wires are fitted into hinges 251, which are provided with a slot 235 having a slot portion 237 extending around the periphery and a vertical slot portion 239 on the front side and rear side of the hinge. By squeezing the wires, the arms can be pivoted through the slot 235. The arms lock into either a front position or rear position when the wires enter the vertical slot portion 239 position, where they expand. When in the wear position, the arms are on the back side of the lens retaining members 250 (FIG. 79).

To fold the glasses, the arms 244 are moved to the front position (FIG. 80) and folded inward at the hinged bridge 248. The concave shaped ear rests are slid up towards hinge 251, and the arms 244 are brought closer to the lens retaining member 251 (FIG. 81). In this arrangement, the open face 255 of the concave shaped ear rests 254 face outward (FIG. 82). The concave shaped ear rests are then rotated to encase the lenses. The concave shaped ear rests can be made of a durable flexible plastic material that facilitates the rotating action.
